Easy -2.0 This is a multiple-choice question testing direct recall of the definition tanh x = sinh x / cosh x, requiring no calculation or problem-solving. It's significantly easier than average A-level questions, which typically require multi-step working.
1 Which expression below is equivalent to \(\tanh x\) ?
Circle your answer.
\(\sinh x \cosh x\)
\(\frac { \sinh x } { \cosh x }\)
\(\frac { \cosh x } { \sinh x }\)
\(\sinh x + \cosh x\)
